GROUNDING INSTRUCTIONS
This product must be grounded. If it should
malfunction or breakdown, grounding provides
a path of least resistance for electric current to
reduce the risk of electric shock. This product
is equipped with a cord having an equipment-
grounding conductor and a grounding plug. The
plug must be plugged into an appropriate outlet
that is properly installed and grounded in
accordance with all local codes and ordinances.
DANGER – Improper connection of the
equipment-grounding conductor can result in
a risk of electrocution. Check with a qualified
electrician or service personnel if you are in
doubt as to whether the outlet is properly
grounded. Do not modify the plug provided with
the product – If it will not fit the outlet, have a
proper outlet installed by a qualified electrician.
Do not use any type of adaptor with this product.

prong grounding-type plugs and 3-pole cord
connectors that accept the plug from the
product. Use only extension cords that are
intended for outdoor use. These extension
cords are identified by a marking “Acceptable
for use with outdoor appliances; store indoors
while not in use.” Use only extension cords
having an electrical rating not less than the
rating of the product. Do not use damaged
extension cords. Examine extension cord before
using and replace if damaged. Do not abuse
extension cord and do not yank on any cord to
disconnect. Keep cord away from heat and
sharp edges. Always disconnect the extension
cord from the receptacle before disconnecting
